very large 3-axis 72"-55" project starting

[haylspa]

hello people well I have designed things for a long time but never really got any thing built do to lack of funds/knowledge of machines that would help I of cores found out what a cnc machine was and have been buying parts to make one from scratch I have had one invention/design stolen I have one other I sell but is hardly any thing I care for (no love for it) well the jift is after finding my design online with the guy I talked to about it back in 2000-2001 I was a little pist and I don't really care to let every thing keep collecting dust on paper

so here is what I have collected so far
3-490oz 2ph stepper motors
3-kl-4030 stepper drives
1-6axis breakout board
1-36v 9.6a p-s
1-1600kw 2hp 24,000rpm liq-cooled spindle
1-1600kw vfd 220v to match spindle
2-lead screws 72"+55"
4-baring mounts(for lead screws)
3-stepper motor mounts
1-v-indexer up to 6" chuck
4-leaner 20mm pillows/bearings

still on list
1-lead screw for z-axis (14-18" travail)
2-72 1-1/4" leaner rods (fully supported)
2-55 20mm leaner rods (semi supported)
2-16mm hollow leaner shafts (for z-axis)
4-20mm shaft mounts
4-1-1/4" shaft mounts
4-1-1/4 pillows
1-er-stop switch
1-home/limit switch?? info please?
1-laptop with windows-xp
1-coolant pump (spindle)
1-coolant reservoir (spindle)
1-coolant radiator (spindle)
1-coolant pump (work)
1-coolant reservoir (work)

frame hardware
4-72" 3-1-1/2" t6 alum 1/4wall
4-55" 3-1-1/2" t6 alum 1/4wall
4-to be determined (still some designing left to z-axis)

the machine is getting started as a 3-axis but is going to end at a 6axis
with the other 3-axis being removable from the work tray

it's length was determined because it will also be used to make molds for body parts (green foam as base form) I figured if I was going to build one I should make it to do every thing rather then make multi-cnc machines

the first 3axis plus spindle is over head and a non moving work tray
will be a concealed cabinet with a funnel screen and filtering set up under the work tray making it really an over sized bench top machine you can use in the house

but I am sure I am missing a lot of need to get components so I am asking if any one has some links for some components parts and suggestions they may have

also if any one has any good places to get some pillow blocks for 1-1/4" that don't cost a $100 or more a piece please let me know or at least a 72"20mm leaner shaft (1-1/4 or larger is all I can find in 72" at a 3time mark up for the pillows bearings etc)

thanks every one in advance

...and no pics, huh?

Sorry to be OT here, but....

Curious as to why you would want to see a bunch of parts laying on the floor or table?

IMO the few words he use to discribe each part just about covers it.

Now picture of his build, that's what I like to see.

its parts collecting at this time no real pics of a started project to show but I can try and get some pics on here soon of the parts if every one would like? or may be try to draw out some rough-draft plans for every one??

go ebay, look for seller "linearmotionbearings" from china...

he got VFD & spindle too... good price.

as for the stepper motor, go for Motion King... simply email their marketing person.

I got 693 Oz.in NEMA34 stepper for US$50. Shipping will offset that a bit, but still cheap.

I already have my steppers vfd and spindle the other place don't make them long enough for my project but thanks for trying

I do have one good advise for every one though don't buy leadscrews from precision tech machining every one of the screws that I got from them where
bent even the replacements bent!!! sent them back one time they said they where not bent got them back bent as hell

still trying to find some good rails but the length I am trying to get has become a nightmare every thing seems to get ruined during shipping or a company that don't know how to send any thing strait

I sure wish I would have seen this post before I ordered a 48" lead screw kit from Precision Tech Machining. Not only did my lead screw get bent in shipment as mentioned above but the bearing journals were machined too large to fit the bearing blocks that came with the order. Once they got my credit card number it was impossible to get order status information from Wanda, the owner, by phone or email, and the few times she did give me status it turned out to be a lie. Fortunately I only spent $107 with them because it all had to be scrapped.

I originally made this video for Wanda to show here the condition of the package I received but she never bothered to look at it. So I did a little voice over so potential future customers of Precision Tech Machining can judge for their self.
